Nursing Elites

1. A patient’s most recent diagnostic imaging has revealed that his lung cancer has metastasized to his bones and liver. What is the most likely mechanism by which the patient’s cancer cells spread?

• A. Hematologic spread
• B. Lymphatic circulation
• C. Invasion
• D. Angiogenesis

Correct answer: B

Rationale: In the case of lung cancer that has metastasized to the bones and liver, lymphatic circulation is a key mechanism by which cancer cells spread from the primary tumor site to distant organs. Cancer cells can invade nearby lymphatic vessels and travel through the lymphatic system, eventually reaching lymph nodes and spreading to other tissues and organs. This route is significant in the metastasis of many types of cancer, including lung cancer.

2. The nurse is caring for a client following radical neck dissection and creation of a tracheostomy. Which assessment finding would indicate an immediate need for intervention?

• A. Frequent swallowing
• B. Presence of mucous membranes
• C. Bubbling in the water-seal chamber
• D. Inspiratory stridor

Correct answer: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.

3. A nurse is caring for a client admitted for Non-Hodgkin’s lymphoma and chemotherapy. The client reports nausea, flank pain, and muscle cramps. What action by the nurse is most important?

• A. Request an order for serum electrolytes and uric acid.
• B. Increase the client’s IV infusion rate.
• C. Instruct assistive personnel to strain all urine.
• D. Administer an IV antiemetic.

Correct answer: A

Rationale: The client's symptoms of nausea, flank pain, and muscle cramps are suggestive of tumor lysis syndrome (TLS), a potentially life-threatening complication of chemotherapy in which cancer cells break down rapidly, releasing large amounts of intracellular components into the bloodstream. This leads to imbalances in electrolytes (elevated potassium, phosphate, and uric acid levels, with low calcium levels), which can cause severe metabolic disturbances, including kidney damage, arrhythmias, and muscle cramps. Checking serum electrolytes and uric acid levels is crucial for diagnosing and managing TLS early, preventing further complications.

4. In an adult patient, which assessment finding is considered diagnostic of Hodgkin lymphoma?

• A. Schwann cells
• B. Reed-Sternberg cells
• C. Lewy bodies
• D. Loops of Henle

Correct answer: B

Rationale: The correct answer is B: Reed-Sternberg cells. In Hodgkin lymphoma, the presence of Reed-Sternberg cells in lymph node biopsy is diagnostic. These cells are large, atypical cells originating from B-lymphocytes. They are distinctive in appearance and are key to diagnosing Hodgkin lymphoma. Choices A, C, and D are incorrect because Schwann cells are related to nerve function, Lewy bodies are associated with Parkinson's disease, and Loops of Henle are structures in the kidney, none of which are specific to Hodgkin lymphoma.

5. An oncology nurse educator is providing health education to a patient who has been diagnosed with skin cancer. The patient’s wife has asked about the differences between normal cells and cancer cells. What characteristic of a cancer cell should the educator cite?

• A. Malignant cells contain more fibronectin than normal body cells.
• B. Malignant cells contain proteins called tumor-specific antigens.
• C. Chromosomes contained in cancer cells are more durable and stable than those of normal cells.
• D. The nuclei of cancer cells are unusually large, but regularly shaped.

Correct answer: B

Rationale: Malignant (cancer) cells often express tumor-specific antigens (TSAs), which are proteins or markers on the surface of cancer cells that are not found on normal cells. These antigens are produced due to genetic mutations in cancer cells and can sometimes be used to help the immune system recognize and attack cancerous cells. Tumor-specific antigens play a key role in cancer diagnosis, monitoring, and targeted therapies.
